EarthFri, 22 Jul 2011 11:04:22 EDTnews230551451New data reveals how storms are triggered in the SahelIn the Sahel, the frequency of storms increases when soil moisture varies over a few kilometers. Such contrasts cause air circulation between dry and humid areas, contributing to the development of storms. For the first time, these contrasts have been studied on a small scale by a collaboration between French researchers from the Groupe d'Etude de l'Atmosphere Meteorologique (CNRS) and UK researchers from CEH, as part of the AMMA project. Their findings, published in the July 2011 issue of Nature Geoscience, provide new data that should help to address the issue of drought in the Sahel.http://phys.org/news227885683.html

While current theory has suggested that soil moisture has had a positive impact on precipitation, there have been very few large-scale observations of this. A team of researchers from Columbia Engineering, Geophysical Fluid Dynamics Laboratory, and Rutgers University has now demonstrated that evaporation from the land surface is able to modify summertime rainfall east of the Mississippi and in the monsoonal region in the southern U.S. and Mexico. One of their main findings is that evaporation from the land is, however, only able to modify the frequency of summertime rainfall, not its quantity.http://phys.org/news226497082.html

BiologyThu, 24 Feb 2011 17:03:35 EDTnews217789403Scientists find new farming method to reduce greenhouse gases, increase farm yieldsU.S. agricultural practices create 58 percent of nitrous oxide in the world, which is the third most prevalent greenhouse gas in the atmosphere. Scientists believe nitrous oxide contributes to global warming about 300 times more than carbon dioxide. New practices and products have been introduced to address this issue, but farmers do not have the time or profit margins to experiment with ideas that may ultimately hurt the "bottom line." Now, researchers at the University of Missouri have found methods to help farmers reduce those emissions while also increasing corn grain production.http://phys.org/news214138382.html

Using broad measurements taken in southeastern Europe,a study demonstrates that the moisture contained in soils play an essential role for these extremes. Compared to wet summers, the frequency of very hot days increases tenfold in summers with dry soils.
